Lost APPLE iTunes yesterday when V 11.1.4 "Upgrade" downloaded on Win 7 pc.....got message MSVCR80.dll is missing; tried to uninstall Apple components to reinstall but uninstall of 2 components failed so can't reinstall. Apple Forum reports that the 'world' must have this problem now.....(for those of us who downloaded the 11.1.4 Update Jan. 23/24, that is) !
